Step 2: Install CDH Using the Wizard

After Cloudera Manager Server has started up, log in to the Cloudera Manager Admin Console:

In a web browser, go to http://<server_host>:7180, where <server_host>
is the FQDN or IP address of the host where the Cloudera Manager Server is running.

Log into Cloudera Manager Admin Console. The default credentials are:

Username:admin

Password:admin

Note: Cloudera Manager does not support changing the admin username for the installed account. You can change the
password using Cloudera Manager after you run the installation wizard. Although you cannot change the admin username, you can add a new user, assign administrative
privileges to the new user, and then delete the default admin account.

After you log in, the End User License Terms and Conditions page displays. Read the terms and conditions and then check the box labeled Yes, I accept the End User License Terms and Conditions to accept them. Click Continue, and the installation wizard launches.

The following instructions walk you through the Cloudera Manager installation wizard for Cloudera Manager.

See Managing Licenses.

If you select Cloudera Enterprise, install a license:

Click the Select License File field.

Browse to the location of your license file, click the file, and click Open.

Click Upload.

Information is displayed indicating what the CDH installation includes. At this point, you can click the Support
drop-down menu to access online Help or the Support Portal.

Click Continue to proceed with the installation.

Welcome

The Welcome page lists the software that will be installed. Click Continue to proceed with the installation.

Specify Hosts

Choose which hosts will run CDH and other managed services

To enable Cloudera Manager to automatically discover hosts on which to install CDH and managed services, enter the cluster hostnames or IP addresses. You can also specify hostname and
IP address ranges. For example:

Note: Unqualified hostnames (short names) must be unique in a Cloudera Manager instance. For example, you cannot have both host01.example.com and host01.standby.example.com managed by the same Cloudera Manager Server.

You can specify multiple addresses and address ranges by separating them with commas, semicolons, tabs, or blank spaces, or by placing them on separate lines. Use this technique to make
more specific searches instead of searching overly wide ranges. Only scans that reach hosts running SSH will be selected for inclusion in your cluster by default. You can enter an address range that
spans over unused addresses and then clear the nonexistent hosts later in the procedure, but wider ranges require more time to scan.

Click Search. If there are a large number of hosts on your cluster, wait a few moments to allow them to be discovered and shown in the wizard. If the
search is taking too long, you can stop the scan by clicking Abort Scan. You can modify the search pattern and repeat the search as many times as you need until you see
all of the expected hosts.
Note: Cloudera Manager scans hosts by checking for network connectivity. If there are some hosts where you want to install services that are not
shown in the list, make sure you have network connectivity between the Cloudera Manager Server host and those hosts, and that firewalls and SE Linux are not blocking access.

Verify that the number of hosts shown matches the number of hosts where you want to install services. Clear host entries that do not exist or where you do not want to install
services.

Click Continue.

The Select Repository screen displays.

Select Repository

Important: You cannot install software using both parcels and packages in the same cluster.

Select the repository type to use for the installation. For this proof-of-concept cluster, select Use Parcels (Recommended).

Select the version of CDH to install. If you do not see the version you want to install, click the More Options button to add the repository URL for
your version. Repository URLs for CDH 6 version are documented in CDH 6 Download Information. After adding the repository, click Save Changes and wait a few seconds for the version to appear. If your Cloudera Manager host uses an HTTP proxy, click the Proxy Settings
button to configure your proxy.
Note: Cloudera Manager only displays CDH versions it can support. If an available CDH version is too new for your Cloudera Manager version, it is
not displayed.

Specify any Additional Parcels you want to install. If you are installing CDH 6, do not select the KAFKA,
KUDU, or SPARK parcels, because they are included in CDH 6.

Select the specific release of the Cloudera Manager Agent you want to install on your hosts. You can choose either the version that matches the Cloudera Manager Server you are
currently using (recommended) or specify a different version in a custom repository. If you opted to use custom repositories for installation files, you can provide a GPG key URL that applies for all
repositories. Repository and GPG key URLs are documented in CDH 6 Download Information.

After reading the license terms and checking the applicable boxes, click Continue.

The Single User Mode page displays.

an account that has password-less sudo privileges.

Select an authentication method:

If you choose password authentication, enter and confirm the password.

If you choose public-key authentication, provide a passphrase and path to the required key files.

You can modify the default SSH port if necessary.

Specify the maximum number of host installations to run at once. The default and recommended value is 10. You can adjust this based on your network capacity.

Click Continue.

The Install Agents page displays.

Install Agents

The Install Agents page displays the progress of the installation. You can click on the Details link for any host to
view the installation log. If the installation is stalled, you can click the Abort Installation button to cancel the installation and then view the installation logs
to troubleshoot the problem.

If the installation fails on any hosts, you can click the Retry Failed Hosts to retry all failed hosts, or you can click the Retry link on a specific host.

After installing the Cloudera Manager Agent on all hosts, click Continue. The Install Parcels page displays.

Install Parcels

The Install Parcels page reports the installation progress of the parcels you selected earlier. After the parcels are downloaded, progress bars appear
representing each cluster host. You can click on an individual progress bar for details about that host.

After the installation is complete, click Continue.

The Inspect Hosts page displays.
